Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The LHCb Collaboration has reported resonant activity in the channel $D^+ K^-$, identifying two components: $X_0(2900)$ with $J^P = 0^+$ at $2866 {pm} 7$ MeV, $Gamma_0=57{pm} 13$ MeV and $X_1(2900)$ with $J^P = 1^-$ at $2904 {pm} […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Peter Berczik, Manuel Arca Sedda, Margaryta Sobolenko, Marina Ishchenko, Olexander Sobodar | Summary: In this work we study the stellar-dynamical hardening of unequal mass supermassive black hole (SMBH) binaries in the central regions of galactic nuclei. We present a comprehensive set of direct N-body simulations of the […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Kevin Langhoff, Yasunori Nomura, , , | Summary: In understanding the quantum physics of a black hole, nonperturbative aspects of gravity play important roles. In particular, huge gauge redundancies of a gravitational theory at the nonperturbative level, which are much larger than the standard diffeomorphism and relate […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Kohei Hayashi, Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai | Summary: Self-interacting dark matter (SIDM) has gathered growing attention as a solution to the small scale problems of the collisionless cold dark matter (DM). We investigate the SIDM using stellar kinematics of 23 ultra-faint dwarf (UFD) […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Mohammad Akhshik, Katherine E. Whitaker, Gabriel Brammer, Guillaume Mahler, Keren Sharon | Summary: We present a novel Bayesian methodology to jointly model photometry and deep Hubble Space Telescope (HST) 2d grism spectroscopy of high-redshift galaxies. Our requiem2d code measures both unresolved and resolved stellar populations, ages, […]
Kavli Affiliate: Robert L. Byer | First 5 Authors: Uwe Niedermayer, Dylan S. Black, Kenneth J. Leedle, Yu Miao, Robert L. Byer | Summary: We demonstrate a compact technique to compress electron pulses to attosecond length, while keeping the energy spread reasonably small. The technique is based on Dielectric Laser Acceleration (DLA) in nanophotonic silicon […]
Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, , , , | Summary: Bivariant theory is a unified framework for cohomology and Borel-Moore homology theories. In this paper, we extract an $infty$-enhanced bivariant homology theory from Gaitsgory-Rozenblyum’s six functor formalism. | Search Query: ArXiv Query: search_query=au:”Tomoyuki Abe”&id_list=&start=0&max_results=10 Read More
Kavli Affiliate: J. S. Villasenor | First 5 Authors: Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, , , | Summary: We analyze in full-detail the geometric structure of the covariant phase space (CPS) of any local field theory defined over a space-time with boundary. To this end, we introduce a new frame: the "relative bicomplex framework". […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Chitraang Murdia, Yasunori Nomura, Pratik Rath, , | Summary: Motivated by the understanding of holography as realized in tensor networks, we develop a bulk procedure that can be interpreted as generating a sequence of coarse-grained holographic states. The coarse-graining procedure involves identifying degrees of freedom entangled at […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: André Melo, Chun-Xiao Liu, Piotr Rożek, Tómas Örn Rosdahl, Michael Wimmer | Summary: Tunneling conductance spectroscopy in normal metal-superconductor junctions is an important tool for probing Andreev bound states in mesoscopic superconducting devices, such as Majorana nanowires. In an ideal superconducting device, the subgap conductance obeys specific […]
